The present invention relates to a machine for cutting off bands in certain lengths, and the machine is also constructed. in such a manner, that the lengths of thebands in an easy and convenient manner may be varied within certain limits.

The invention is shown in the accompanying drawing, in which Figure 1 is a front view of the machine. Figure 2 is a side view of the same. Figure 3 is a plan view of the same. In the drawing 1 indicates a stand or a socle, which at one end has a bearing 2, in which a friction plate 3- is rotatably mounted, which at the same time serves as a fly-wheel. At the other end of the socle two friction rollers 4.- and -5 are rotatably mounted. The roller 4 is keyed on a shaft -6, which extends towards the bearing 2- and is parallel with the plate 3, so that the axis of the same crosses the axis of the plate 3. The roller 5.'

' ought to be mounted somewhat yielding i the vertical direction owing to the different thickness of the bands which the rollers are to convey. On the shaft 6- a friction wheel is arranged slidably but not rotatably, which wheel is in constant engagement with the friction plate 3-. The wheel 7 is mountedon the shaft 6 by means of an arm 8, which is connected with the hub of the wheel 7, so that this wheel may rotate relative to the arm, which is loosely placed on the shaft 6--. At the free end the arm 8' has a head bolt -9-, which is in engagement with'a slot 10 in the stand 1, and which by a winged nut -11 may be fastened in such a manner, that the arm 8 with the wheel 7 is kept in the desired position on the shaft 6 connection with the arm -8 a scale 12 may be:arranged on the stand, which indicates the' lengths of the bands which are cut off. The cutting device itself consists of a rotatable roller 13, mounted on the plate -3, which roller extends somewhat in front of the circumference of the plate. This roller co-acts with a knife l4, which is pivotally mounted on the stand, and

which by a spring -15 is kept in the normal position shown in the drawing, lying against a button 16- with the cutting edge lying directly above a slit 17, through which the band arrives, conveyed by the roll- I ers 4-5. That part of the knife 14, which oo-acts with the roller -13- is formed with a slanting surface 18. In the performance shown in the drawing, which is adapted to be driven by hand, a handle --19 is fixed to the friction plate The machine operates in the following manner: I

Suppose that a .band is inserted between the rollers -45' and that the plate 3- is rotated in the direction indicated by the arrow, then the wheel 7, the shaft -6 and the rollers +5- will be made rotating and conveying the band a certain length for each revolution of the plate 3-. 7 Each time the roller -13 strikes against the slanting surface 18 of the knife -14, the same will swing down round its pivot and cut off the band, conveyed through the slit 17 by the rollers 45. After the roller 13-'- has passed the knife, the same will again by the spring be brought back in its normal position, lying against the button 16. It will be'understood that by placing the friction wheel 7- at a smaller or greater distance from the axis of rotation of the plate 3, the lengths of the bands cut off will be shorter or longer.

The performance shown in the drawing is only given as an example, as alterations may be made without departing from the scope of the invention. For instance the machine may be constructed to be driven mechanically and arranged in such ,a manner, that for each revolution of the disc more than one band is cut off. By substituting the knife 1l with a counting apparatus, which is acted on by the roller 13 during the rotation of the disc 3-, the machine can also effectively be used for measuring bands.

What I claim is:

1. In combination with feeding rolls of means for cutting the product delivered from said rolls in predetermined lengths, comprising a shaft connected to one of said rolls, a 100 friction driven diskfor driving said shaft adapted, to slide lon 'tudinally with resgfscli to said shaft, a rotata 1e friction driving disposed parallel to said shaft and adapted to frictionally engage said driven disk for driving said shaft, means for maintaining said driven .disk in any desired position along a line onthe friction disk parallel to said shaft, a shear for cutting the product, means on said driving disk for mechanically actuating said cutting shear, and means for rotatv I ing said driving disk.

2. In combination with feeding rolls, of means for cutting the product deliveredfrom said rolls in predetermined lengths comprisa shaft connected .to .one 0 drlven disk slidable longitudinally on said shaft and adapted to rotate said shaft, a rotatable friction driving disk disposed parallel to said shaft and frictionally engaging said driven disk, means for maintaining said driven disk in any desired position along a line on the friction disk parallel to said shaft, a scale graduated to indicate the lengths of the product severed, a shear for cutting the product, means on the circumference of said driving disk adapted to mechanically actuate said cutting shear, and means for rotatin said driven disk.

In testimony w ereof I have signed my name to this specification.
